Ukraine war: Russian troops forced out of eastern town Lyman

Ukraine's forces have mounted a sweeping counter-attack to re-take territory in the east

Russia has withdrawn its troops from the strategic Ukrainian town of Lyman, in a move seen as a significant setback for its campaign in the east.

The retreat came amid fears thousands of soldiers would be encircled in the town, Russia's defence ministry said.

Recapturing Lyman could let Ukrainian soldiers reach more contested territory in the Donetsk and Luhansk regions.

Ukraine's President Volodymyr Zelenky said on Sunday the town had been "completely cleared" of Russian troops.

Video footage shared online on Saturday - before the Russian retreat was announced - showed Ukrainian soldiers waving their national flag on the outskirts of the town.

Lyman had been used as a logistics hub by Russia, making its recapture all the more significant to Ukrainian forces.

The battlefield setback prompted the Chechen leader and hardline Moscow ally, Ramzan Kadyrov, to comment that Russia should consider using low-yield nuclear weapons in the face of such defeats.

Lyman is in Donetsk - one of four partially-occupied Ukrainian regions which Russia declared it was annexing on Friday. Ukraine and its Western allies have dismissed the move as an illegal land-grab.

An adviser to Ukraine's defence minister earlier told the BBC that recent gains around Lyman - following days of intense fighting - represented a "considerable success".

Russian fighters had been given the chance to surrender, Yurik Sak said, and would face better treatment as prisoners of war than from the Russian military leadership.

Shortly afterwards, the Kremlin said it was withdrawing its forces from the town, using its Soviet-era name of Krasnyi (Red) Lyman, acknowledging that the Ukrainians had "significant superiority in forces" in the area.

Military analysts say that Kyiv currently has momentum in the war, and it has vowed to forge ahead with a counter-offensive to reclaim all territory under occupation.

In a speech on Friday, Mr Zelensky said efforts to "liberate our entire land" would act as proof that international law could not be violated.
